Previously it was mapped (as a default) to `G_IO_ERROR_FAILED`.
It’s the error that macOS returns when trying to connect to a socket which
is bound but not listened to. Linux returns `ECONNREFUSED` in this case.
It’s helpful if they both map to the same `GIOError` value.
This should fix the `/socket-client/connection-fail` test on macOS,
which is currently
[failing](https://gitlab.gnome.org/GNOME/glib/-/jobs/3970547) with:
```
# GLib-GIO-DEBUG: GSocketClient: Starting TCP connection attempt
# GLib-GIO-DEBUG: GSocketClient: Connection attempt failed: Can't assign requested address
# GLib-GIO-DEBUG: GSocketClient: Starting new address enumeration
# GLib-GIO-DEBUG: GSocketClient: Address enumeration completed (out of addresses)
# GLib-GIO-DEBUG: GSocketClient: Address enumeration failed: (null)
# GLib-GIO-DEBUG: GSocketClient: Connection failed: Could not connect to localhost: Can't assign requested address
not ok /socket-client/connection-fail - GLib-GIO:ERROR:../gio/tests/gsocketclient-slow.c:231:test_connection_failed: assertion failed (local_error == (g-io-error-quark, 39)): Could not connect to localhost: Can't assign requested address (g-io-error-quark, 0)
Bail out!

See: #3184Fixes: #3394
Avoid re defining cases for GIoErrorEnum when we already handle them
through GFileError, so remove code duplication and just rely on
g_file_error_from_errno() to compute the file error and then use
g_io_error_from_file_error() to get the possible IOError.
In case it's something not handled as GFileError, we can use the same
logic as before.
This is now a safe change to do as we have covered all the supported
cases in tests.
Add SPDX license (but not copyright) headers to all files which follow a
certain pattern in their existing non-machine-readable header comment.

`ENXIO` can be returned from `open(2)` for special files (FIFOs, device
files and domain sockets) which are not backed by anything.
This fixes the error returned by `g_file_replace()` when trying to
replace such a file, so that it now matches the documentation.

This has almost the same semantics as WSAECONNRESET and for all
practical purposes is handled the same. The main difference is about
*who* reset the connection: the peer or something in the network.
For UDP sockets this happens when receiving packets and previously sent
packets returned an ICMP "Time(-to-live) expired" message. This is
similar to WSAECONNRESET, which on UDP sockets happens when receiving
packets and previously sent packets returned an ICMP "Port Unreachable"
message.
instead of using a generic G_IO_ERROR_FAILED error code.
This is in line with what W32 part of the code is doing with WSAENOTSOCK.
This fix will break two tests in libsoup, which were written following
the implementation and thus expect G_IO_ERROR_FAILED when attempting to
do stuff with no-longer-valid socket descriptors.
Mention that it really is a good idea to save errno before doing
literally anything else after calling a function which could set it.

Add G_IO_ERROR_CONNECTION_CLOSED as an alias for
G_IO_ERROR_BROKEN_PIPE, and also return it on ECONNRESET.
It doesn't really make sense to try to distinguish EPIPE and
ECONNRESET at the GLib level, since the exact choice of which error
gets returned in what conditions depends on the OS. Given that, we
ought to map the two errors to the same value, and since we're already
mapping EPIPE to G_IO_ERROR_BROKEN_PIPE, we need to map ECONNRESET to
that too. But the existing name doesn't really make sense for sockets,
so we add a new name.

Rather than having special code in gsocket.c, handle Winsock errors
along with other Win32 errors in gioerror.c
Also, reference g_win32_error_message() from the
g_io_error_from_win32_error() docs, and update the
g_win32_error_message() docs to clarify that it works with Winsock
error codes too.
Map EPROTONOSUPPORT, ESOCKTNOSUPPORT, EPFNOSUPPORT and EAFNOSUPPORT to
G_IO_ERROR_NOT_SUPPORTED in g_io_error_from_errno(). (GSocket's
socket_io_error_from_errno() already did this with the corresponding
Winsock errors.)
Also map EOPNOTSUPP, which on Linux is the same as ENOTSUP, but may
not be on other platforms.
Also, rewrite the EAGAIN/EWOULDBLOCK section to use the simpler idiom
used by EEXIST/ENOTEMPTY and (now) ENOTSUP/EOPNOTSUPP.
Correspond to GUnixInputStream and GUnixOutputStream. No true async
support though. But that is how the Win32 API is, for files not
explicitly opened for so-called overlapped IO.
The API to create these streams takes Win32 HANDLEs. Not file
descriptors, because file descriptors are specific to the C library
used. The user code and GLib might be using different C libraries.
Also add a test program for the new classes, and a gio-windows-2.0.pc
file.
This adds:
GInitable - failable object constructor interface
GAsyncInitable - async failable object constructor interface
GSocket - Platform independent lowlevel berkely socket style object
GSocketControlMessage - For passing control messages over GSocket
GUnixFDMessage - unix fd passing socket control message
Some changes were done during the import from gnio to make things
work in glib. For instance, types were moved to other headers, header
file boiler plate were updated to glib style and gio.symbols stuff
was added.
